- RECORDING-CLOCK.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed August 12, 1903. Serial No. 169,264.

To all whom it may concern:

Be it known that I, ADOLF KOPEKIN, a citizen of Russia, and residing at Vienna, IX Porzellangasse No. 8, in the Province of Lower Austria, Austria Hungary, watchmaker, have invented certain new and useful Improvements in Recording-Clocks, of which the following is a full, clear, and exact specification.

This invention relates to improvements in recording clocks and has for its object to provide a watchmans clock in which a device with a writing surface provided with time graduations is caused to pass a recess or opening arranged in the closed casing, according to the run or movement of the works of the clock, the arrangement being such that that part of the writing surface which is exposed by said recess or opening, is to receive the name, signature or any conventional sign from the person to be controlled.

In order to make my invention fully understood, I have appended a sheet of drawings embodying the same.

Figures 1 and 2 show a recording clock ac cording to my invention, having two writing for the hour hand spindle and one for the minute hand spindle. Fig. 3 represents'a writing surface for such clock. Fig. 4 is another form of construction of the clock having the writing surface arranged on the dial side thereof. Fig. 5

by way of example, an arrangement or contrivance for attaching the writing surface to the spindles of the hands of the clock.

Referring to the above drawings, the invention is based on the principle of moving the surfaces or faces A behind a recess or opening a arranged in a casing 1 inclosing said faces or surfaces, so as to pass such recess or opening and thus expose its various parts intended to be laid free through said recess or opening. The latter is made large enough to enable the person to be recorded to sign his name or place anyrequired mark or sign on the surface thus exposed.

The casing 1 which incloses the writing surface may be represented by the clock casing itself as shown in Figs. 1 to 4, and it is in this case immaterial as to which wall of the clock is provided with the recess or opening. Figs. 1 and 2, for example, show the back wall I) fitted with such opening, while according to Fig. 4 the said opening a is arranged in the front wall 0. In cases of the writing surfaces being arranged in the clock casing itself, it is preferable to have them moved or actuated and carried alone respectively by the spindle of the hour wheel, the arrangement of the clock remaining thereby unaltered. The speed at which the writing surfaces are moved depends on the number of the records to be made in the respective unit of time, but as a rule, the same velocity as that of the hour hand, that is to say, once in every 12 or 24 hours, is adopted.

Behind the writing surface a bridge-like plate 9 is arranged opposite the recess or opening a to serve as a backing for the record disks or dials A, B, when the record is being made.

The form of construction of the clock shown in Figs. 1 to 3, enables several records to be made within a short time interval. Writing surfaces A and B are here provided one upon the hour wheel spindle i and one upon the minute hand spindle is, a copying sheet of indigo, carbon or graphite paper I) or the like being interposed between them. B making one rotation within an hour, a large number of signatures or signs may be recorded upon its surface; said dial B is thereby pressed against A arranged upon the spindle i, so that such signatures or signs are transferred by means of the transfer paper to the dial A within the space corresponding to the respective division of the hour. This arrangement has the additional advantage, that the signature or sign recorded upon the surface, rapidly moves from under the opening a and disappears behind the plate B. The same arrangement of the two writing surfaces may be made use of in all forms of construction of the clock; it is only necessary that the surface A should be moved synchronously with the run of the clock, while the surface B is moved at any higher speed. In order to exactly determine the time of recording the signature or sign, each Writing surface is provided with a line above or below the signature or sign (according to the direction of movement of the writing surface) and along the border edge. of the recess or opening a, such line indicating the exact graduation mark upon such surface.

The fastening or securing of the writing surfaces upon the actuating spindles may be effected in any suitable manner, a preferable mode of fastening or securing is illustrated in Fig. 5. Upon the end of each spindle 5 and 7c is mounted a carrying disk m and n respectively, having projections or studs upon which thejsurfaces are pressed. Above the said projections or studs of each carrying disk is placed a covering ring 1 provided with a clamp 19 influenced by a spring; said clamp being kept in position by its friction upon the projections or studs and if desired, catching or engaging in, small recesses, thereby preventing the disks from dropping down, and securing them against a displacement in respect of each other'respectively. The covering ring may in addition, be provided at its underside with springs q for keeping the writing surfaces in position. The dial A is provided at its peripheral edge upon the face adjacent to the paper I) with a series of graduations or division lines a corresponding to the hours and divisions thereof, while the dial B is provided upon its outer face at its peripheral edge with a series of graduations or division lines If corresponding to the minutes.

Inasmuch as the surface A moves considerably slower than the surface B, there would be danger of the names written upon the surface B and copied through on to the surface A overlapping which would destroy the utility of the device, but I would state that the apparatus is adapted for use only where there would be a comparatively few names or marks written upon the surface B within the space of one hour so that the surface A wou d move sufficiently during the interval between the writing of two different names to prevent such names overlapping. Of course the device could be used for indieating a considerable number of rounds of f the watchmen within the space of an hour if only small marks or indices were used by the watchman instead of writing his name each time.

I claim:

In a recording clock, the combination with a casing, a wall of which is provided with an opening, of the hour wheel and minute hand spindles, two writing surfaces, one mounted upon the hour wheel spindle and the other mounted on the minute hand spindle respectively, a copying sheet interposed between said two writing surfaces and means for-keeping the said writing surfaces with the copying sheet between them upon their respective spindles, as and for the purpose set forth.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.

ADOLF KOPEKIN.
